Is it important to submerge the bird completely or can it be sticking out a little. I am brining 2 birds in a tub because it fit in the fridge so well. There is a little bit of bird sticking out of the brine. Should I sweat it or are these things like sponges and as long as its in the brine, I'm good.

I fill up a qt. or gal. ziploc bag half full, squeezing the excess air out of it and zip it tight and place on top to hold the bird down in the brine, it works great and a simple, easy solution! I dunk the bird in breast first so it sticks legs up, then hold it down with the bag. Thank you so much for asking!
